Do You Need Part F Ventilation Testing?
What is Part F Ventilation Testing?
Part F of the Building Regulations sets minimum requirements for ventilation in residential buildings to support healthy indoor environments and effective moisture control.
Ventilation testing is undertaken to demonstrate that installed extract ventilation systems achieve the required airflow rates and perform in accordance with Approved Document F. This typically includes testing intermittent extractor fans, continuous Mechanical Extract Ventilation (MEV) systems, and other ventilation strategies used within residential developments.
Demonstrating compliance is an important part of the Building Regulations process and helps ensure buildings provide adequate ventilation for occupants.

Frequently Asked Questions
Part F sets requirements for ventilation in buildings to help maintain indoor air quality and manage moisture levels within occupied spaces.
Most new-build residential developments will require ventilation testing to demonstrate compliance with Building Regulations requirements. If you are unsure, check with your building inspector.
We test intermittent extract fans, Mechanical Extract Ventilation (MEV) systems, and other residential ventilation systems where airflow performance must be demonstrated.
If a system does not achieve the required airflow rates, we can help identify the cause and provide practical recommendations to achieve compliance.
Testing is typically undertaken once systems have been installed and connected to mains electricity.
Common causes include poor ductwork installation, excessive duct lengths, airflow restrictions, back pressure, and insufficient fan power.
